There's a rather nondescript book called "Using Borland C++" by Lee
and Mark Atkinson (Que Corporation) which presents an excellent
discussion of overloaded new and delete operators.
I am presenting below a summary of what I have gathered. I would
appreciate if someone could point out to something that is specific to
Borland C++ and is not supported by the ANSI standard. I am also
concerned that some of the information may be outdated...

Hi all,
I've been using C++ for quite a while now and I've come to the point where I need to overload new
and delete inorder to track memory and probably some profiling stuff too. I know that discussions of
new and delete is a pretty damn involved process but I'll try to stick to the main information I'm looking for
currently. I've searched around for about the last too weeks and have read up on new and overloading it to
some extent but...

I'm having trouble overloading the global operator new and delete. I
want to do this for debugging purposes to trace allocations and
deallocations. What I have is
#ifdef _DEBUG
// User-defined operator new.
void *operator new( size_t stAllocateBlock )
{
static fInOpNew = 0; // Guard flag.

I'm trying to create a basic Heap manager and i have some question

hi I am trying to make some simple app to learn exception safety
coding. I know that new and delete can throw bad_alloc but how can I
force them to throw by a flag "change" at run time?
I am overloading new, new, delete and delete, change is set to 1
then it calls the custom operators. If 0, it calls the c++. But how can
I overload delete and delete?
The original library signature has const std::nothrow_ and throw()
If I overload this,...

The C++ Standard Doesn't Permit Overloading new and delete?
In the 13.5 of The C++ standard (ISO/IEC 14882, 1998), I cannot find
the specification on overloading the operators new and delete; however,
many C++ books including "C++ Primer" say that the operators new and
delete can be overloaded. I wonder if this has definitive
specification? Who can tell me?
Many thanks to those who answer.

As I am newbie to C++, I am confused by the overloading issues. Everyone
says that the four operators can only be overloaded with class member
functions instead of global (friend) functions: (), , ->, =. I wonder
why there is such a restriction.
Some tutorials say that 'new' and 'delete' can only be overloaded with
static member functions, others say that all overloading function should
be non-static. Then what is the fact, and why?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
